The accompanying drawings illustrate my inven-.

tion:

Figure l is a side elevation of a wagon bed embodying my invention, the running gear being omitted; Fig. 2 is a plan; Fig. 3 a rear end elevation; Fig. 4 a transverse section on line 4-4 of Fig. 1; Fig. 5 a section on line 55 of Fig. 1 showing the means for preventing displacement by underrunning of the front Wheels; Fig. 6 a section on line 6-6 of Fig. 1 showing a means for bracing one of the swinging sides; Fig. 7

I a similar detail showing a modified form of brace; Fig.

8 a detail on a larger scale of the means for automatically locking and unlocking the swinging sides; Fig. 9 a detail of the pivotal support for the swinging sides; Fig. 10 a vertical sectional detail on line 1010 of Fig. 9; Fig. 11 a transverse section showing a means for separating the load into halves and for removing any material which may gather on the crown of the intermediate or central ridge; Fig. 12 a detail of one of the supporting brackets for the divider board, and Fig. 13 a detail of the divider board and its supporting pintle.

In the drawings 10 indicates a central inverted V- shaped ridge structure supported at each end by a.

to the outer face of the end board and the cross bar 11,

and the lower ends extended below the lower edge of the bar 11 so as to engage or lap over the adjacent face of the bolster l2 and thus hold the body securely in place on the bolsters 12. In order to further brace the end boards 13 I provide the braces 15, arranged as shown, the lower ends being attached to so much of the central ridge 10 as is projected through and beyond the end board.

Acting in conjunction with the central ridge 10 and the end boards 13 are two similar swinging members each of which comprises a pair of end plates 16 a connecting vertical wall 17, and a downwardly and inwardly inclined bottom 18 connected at its outer edge with the lower edge of side 17 and adapted at its inner edge to mate with the lower edge of the adjacent portion of the intermediate ridge 10. The upper edge of each side 17 is strengthened with a longitudinal bar 19, the ends of which project beyond the end plates 16 and are notched at 20 to receive the upper edge of the adjacent end board 13 (as shown in Fig. 8) which is similarly notched to receive the projected end of the bar 19, the bar 19 when in this position, serving as a brace and support for the upper edge of the adjacent end board. Each of the swinging sides just described is pivotally supported, upon an axis parallel with the central ridge 10, at its upper inner corner, and for convenience of construction I provide the forward plate 16 with a pivot pin 25 adapted to enter a socket 26 formed in the forward end board 13, while the rear plate 16 is provided with a pin 27 having an enlarged head 28. In order to receive the pin 2728, the upper edge of the adjacent rear end board 13 is provided with an open notch 29 fitted to receive the pin 27-28 so that the enlargement 28 thereof will co-act with the end board so as to form a brace therefor, as clearly shown in Fig. 10. In order to hold the pins 2728 in place I provide a plate 30 having a pair of fingers 31 adapted to lie in the upper ends of the notches 29 above the pins 2728, said plate being held in position by a single bolt 32, the arrangement being such that, by removing plate 30, and swinging pin 27-28 upward out of its notch, the entire swinging member of the bed may be shifted longitudinally enough to withdraw pin 25 from its socket 26, whereupon the entire member may be readily withdrawn from the bed.

In order to swing the swinging members of the bed upward readily I provide, near the front end of the wagon, a shaft 35 provided with a suitable operating crank 36. Attached to shaft 35 are lifting cables 37 which are attached to the swinging members at points 38 near their lower edges.

In order to securely hold the swinging members of the bed down in load holding position, I provide a pair of pivoted locking fingers 39, 39 each of which, in its normal position depends from its pivot to a point immediately above the projected end of one of the bars 19, as clearly shown in full lines in Fig. 8. In order to provide means for readily simultaneously operating these two locking fingers, I make the seat in two parts, a front fixed portion 40 and a swinging rear portion 41, attached to the rear edge of portion 40 by suitable hinges 42. Each of the locking fingers 39 is connected by a rope or chain 43 with the swinging member 41 of the seat, the arrangement being such that, when the seat is in normal position, as shown in full lines in Figs. 1 and 2, the ropes 43 will serve to positively draw the locking fingers 39 to locking position. The seat member 41 is provided with an upwardly projected portion 44 which, when the seat member is swung forward, will engage the locking fingers so as to swing them to the position indicated in dotted lines in Fig. 8, thus freeing the bars 19.

The pivot pins for the swinging members of the bed are preferably carried by brackets 45 secured to the end plates 16 and these brackets are preferably secured to the outer faces of these end plates so as to leave a space 46 between the outer faces of these end plates and the inner faces of the end boards 13 so that any accidental lodgment of material adjacent the end boards will not operate to bind the swinging members between them. In order to prevent leakage at the ends of the swinging members the brackets 45 are continued down along the inner edge of the plate 16 so as to form a tight joint with the end board 13, as clearly shown in Fig. 10. The relative sizes of some of the parts are exaggerated in the drawings for convenience in illustrating.

In order to properly brace the inclined bottom members 18 I deem it advisable to provide one or more intermediate braces 50 which, if desired, may assume the form shown in Fig. 7.

v In order to prevent the forward wheels from distorting the bed when a sharp turn is made, I provide each of the swinging members with a wheel plate 51 and immediately adjacent said plate I secure to the inclined bottom 18, a finger or bar 52, the lower inner end of which is projected beneath the lower edge of the adjacent portion of the ridge 10, as clearly shown in Fig. 5, the construction being such that, if the wheel is driven under the bottom 18 against the plate 51, finger 52 will transmit the thrust to the middle ridge 10 and thus prevent any distortion of the bottom 18.

It is desirable many times to dump one side of a load at a time, and for this purpose I provide a divider board 60 provided at each end with a pintle 61 adapted to be dropped into a bracket 62 having a receiving socket 63 open at its upper end, the arrangement being such that the pintle 61 may be readily dropped into or removed from the socket 63. In order to swing the board 60, readily, and thus clear any material which may have lodged upon the top of the ridge 10, I provide an operating lever 64 and, in order to hold the board 60 in its middle position, said lever 64 may be provided with a suitable detent 65 cooperating with a segment 66.

In order to swing the two sections independently the cables 37 are preferably detachably connected to the shaft 35 and, for convenience, I deem it advisable to provide each of the swinging members with a pair of lever-receiving clips 67 adapted to receive an operating lever 68, shown in dotted lines in Fig. 1.

The pivotal axis of each of the swinging members of the bed is arranged as nearly as possible to the medial line of the vehicle and as nearly as possible at the upper inner corner of the swinging section so that, when said section is swung upon its axis all parts thereof will initially move away from the load so that no cramping on or compression of the load results from the swinging of the sections to dumping position. i The pivotal axis of the swinging side section lies in a plane nearer the center of the bed than the inner edge of the bottom 18 and consequently whatever portion of the load acts upon the swinging section has a tendency to swing the section farther inward upon its axis so that the load operates to hold the section in load retaining position. Further than this, the

sides 17, being substantially vertical for a considerable portion of the depth of the section, the side thrust, due to fluidity of the load, would be more than counterbalanced by the weight component acting upon the bottom 18.
